APPARATUS FOR PURIFYING WATER.

SPECIFICATION forming part Of Letters Patent NO. 652,155, dated June 19, 1900.

Application fi ed September 16, 1899. Serial N0- 730,725. (No model.)

To ctZZ whom it may concern.-

Be it known that I, THOMAS E. WINGROVE, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Apparatus for Purifying Water, of which the following is a specification.

This invention relates to an apparatus for purifying Water for icemaking machines, boiler-feed, and other purposes.

The object of the invention is to provide for purifying the water of condensed steam, which contains oil and other impurities, so as to render such water fit for conversion into ice.

In the accompanying drawings, Figure 1 is a diagram in elevation showing the several parts of the apparatus connected together. Fig. 2 is a vertical section of the boiling-tank, filter, and skimming device. Fig. 3 is a vertical section of the regulator. Fig. 4 is a plan of the perforated filter-plate.

The letter A designates a Water-pipe from a steam-condenser; B,'a tank for boiling the water. The end A of the water-pipe prefer ably projects down into the tank to a point near its bottom. A filter O is connected with the tank. A pipe d for pure water leads from the filter, and said pipe finallyconnects With the regulator F. The tank has an overflow device or skimmer, and a pipe 6 for the skimmed impure water leads from the skimmer to the regulator. In the present instance a coil of pipe g, serving as a cooler, and also -a second filter H are interposed in the line of pure-water pipe d.

The tank B contains pipe 1, arranged in two coils on the bottom of the tank, and one or more pipes of the lower series of coils has perforations 2". Steam from a boiler circulates through these coils, and thus the water in the tank B and which is undergoing the pnrifying process is heated and boiled, and steam escaping from the perforations agitates the water. An upright pipe 2' with its upper end open,leads from the lower coils and serves as an outlet for any steam or gas that does not escape at the perforations 11. At the discharge end the tank has a bulkhead or wall 3', which fits tight to the bottom and to the two side walls. A second tight bulkhead or wall j is parallel with the first one, and the space between the two is packed with suitable material to act as a filter C, before men tioned. This filter has a bottom plate It, containing perforations,and also a perforated top plate 70, and a vertical bolt 1 passes through both plates'and holds them in position. Below the filter is a space m, from which the pure-water pipe d leads, and between the second bulkhead or wallj and end 11 of the tank is a space or chamber 12 for the skimmings or impure water, and the pipe e leads from this chamber.

A hood 0 covers the filter 0, being united tightly to the top of the second bulkhead j and extending therefrom over the filter and above the top of the'first bulkhead j, leaving an overflow-space 19 onto the filter and having a downward-projecting flange or baffle plate 0' in front of the said overflow-space. By this construction the oil and light impurities contained in the heated water that is being treated will rise to the top and will be skimmed off or flow over the hood 0 and into the chamber '71 and thence out through impure-water pipe 6 to the regulator. The heated water below the baffie-plate 0 will rise in the spacep, adjoining the bulkheadj, and overflow through the space 19 onto the top plate of the filter and pass down through the filter to space or and then out through purewater pipe d. As already indicated, this water next may go to a cooler g and to another filter H and then to the regulator, or obviously might go direct from the first filter O to the regulator, the cooler and second. filter being omitted.

The regulator F controls the operation of the two kinds of water that leaves the boiling-tank B and insures that the Water c011- taining the oil and light impurities will fiow over the hood 0 and discharge through a pipe, while the purified water that is freed of oil will discharge through aditferent pipe. The regulator comprises an upright cylinder Q, having a hollow piston Q, which reciprocates within it. The impure-water pipe 6 extends downward from the tank B and connects with the cylinder below the piston in order that the pressure exerted on the piston by the weight of water standing'in the uprightpipe (2 will raise the piston Q. A stem 7" is at tached to the piston and projects up and moves through an eye in ayoke s and serves i port 1; and partly fills it.

to guide the piston. A beam or cross-head of suitable kind is connected with the piston Q5 the second valve controls the impure water which wastes from the cylinder, and the joint operation of these two valves is such as to insure the proper operation of the purifying tank B. The port o of the waste-water valve a is much smaller than the port 11 of the purewater valve, and the waste-water valve it also has a stem 10 depending below it, which when the valve is seated projects down through the \Vhen this valve begins to lift or to unseat, the depending stem still remains in the port '1) and partly chokes it, so that the impure Water in the cylinder Q, is allowed to discharge, but only very slowly,

until the piston Q has raised far enough to I which leads to a receiver.

entirely withdraw the depending stem to from port 2:, thereby affording time for the larger quantity of pure water in the pipe (Z to flow out through the open port 0) to the pipe (1', (Notshown.) The impure water that discharges through the port 0" and pipe e goes to waste in a drain or to any suitable place. The cylinder Q-has an air-vent hole x, to which is attached astan'dpipe w, whose upper end is as high as the I ton and the closing of both valves.

purifying-tank B. This air-vent provides for the escape of air from below the piston, and thereby insures that there will be no air present to hinder downward movement of the pis- As the waste-water valve u is smaller and lighter than the other valve, a weight g is attached to the beam or cross-head at the end where the stem 25 of this valve is connected. This weight has a set-screw g, which holds the weight wherever set on the beam.

Now the operation of the apparatus is as follows: Water from a steam-condenser or other source of supply passes from pipe A into the tank B. Steam from a boiler circulates through the coils i in the tank. Also a few steam-jets issue from the perforations t, and these jets agitate the water and also assist to-heat it. The water will fill the tank after the pipe (1 becomes filled, because valve 7.6 is closed. The oil and light impurities will now rise to the surface in the tank and flow over the hood 0, and the water freed from these impurities passes up space 19 and over the bulkhead j, then through the filter G, and thence through pipe d to the closed valve a in the regulator. The water skimmed by flowing over the hood 0 enters the chamber a and then passes through the stand-pipe 6 into the piston-chamber Q. As soon as this stand-pipe is full of Water sufficient pressure will thereby be created to raise the piston Q, which opens both valves to u. The pure water in pipe cl will have ampletime to discharge, be-

cause this valve a will be retained open for a sufiicient period by the comparatively-slower discharge of the impure water through the choked port 4). Then, however, the impure water in the cylinder has been discharged, the piston Q will lower, and thereby both valves will be seated. While these valve movements have been going on, the Water in the tank B maintains its position to the top of hood 0. Were the regulator absent and the discharge water-pipe 01 open the water filling into the tank would never rise high enough to overflow the hood 0, and the skimming operation would not result.

The operation is automatic entirely, and the piston and two valves will alternately raise and lower with a degree of speed in unison with the speed of water flowing into the tank by pipe A.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
